OCC kicked off — after a two-hour delay the athletes still delivered a thrilling battle of speed. Jim Walmsley overtook Cristian Minoggio just before the finish in Chamonix to claim the OCC title, and Yao Miao took the women's runner-up spot. In the earlier-starting PTL category the leaders crossed the line, cutting the record from 99 hours down to 78 hours — a 21-hour improvement. #UTMB #OCC #姚妙 #PTL #跑野大爆炸
